After days of race-tinged social media threats against Anne Arundel County schools, officials say there are no immediate plans to change policies governing how students use their phones in school.

School system spokesman Bob Mosier said there has been an ongoing conversation on social media policy, but no formal changes have been proposed.

"Our teenagers in our society ... live on electronic devices," he said. "That electronic device use has many, many, many positive ramifications to it."

County police stationed additional officers at Arundel and Annapolis high schools Tuesday after two Twitter accounts posted threats targeting the schools. The tweets contained racist statements, with both referring to the Ku Klux Klan and threatening black students.

Lt. Ryan Frashure, a police spokesman, said the early morning tweet was "obviously a copy cat" of a similar threat made against Arundel High on Monday.

The threats appear to be in reaction to a racist petition circulated at Arundel High School last week. It urged students to sign a petition in support of the "Kool Kids Klan," using racist language that disparaged African-Americans. Two students were disciplined.

Frashure said interviews with students suggest the threats this week were likely intended to mock the incident involving the petition.

Officers investigating the incidents spoke with students who said they believe the offenders are doing it because "they think it's funny" and "because they're seeing it in the media," Frashure said.

Posts on Monday included one that came from an account called "kkkforeal," saying it was "blowing up Annapolis High school tomorrow." It followed an online account referring to the "Kool Kids Klan," which threatened "an attack" at Arundel High School and was spotted by school staff members.

One of the two Twitter accounts was still active Tuesday during school hours and had the words "Y'all ready" during school hours.

Mosier said individual schools can dictate their own rules regarding social media platforms like Twitter and Facebook.

Annapolis and Arundel high schools, unlike some other county high schools, do not have designated times when students are allowed to use electronic devices, Mosier said.

Both schools allow teachers to incorporate the use of the devices into their instruction. Mosier said this can benefit the teaching of current events, as it did when information about the 2013 Boston Marathon bombing was disseminated through Twitter in the hours following the attack.

"That, of course, does not mean that student don't necessarily text, for instance, between classes or at lunch," Mosier wrote in an email.

Police said that even when they suspect social media threats are pranks, they must handle them as they would any other threat.

Frashure said it will be difficult to pinpoint the offenders based on their accounts alone.

Police have to obtain a subpoena for Twitter to gain information about the users, a lengthy task not guaranteed to yield useful results. Twitter users do not need to verify their identity to sign up and IP addresses can simply lead to computers at the schools rather to individuals.

In a letter to parents following Tuesday's incident, Annapolis High School Principal Sue Chittim urged parents to "take a minute tonight to talk to your child about the events that unfolded today."

"The lack of appreciation for diversity to which our children are exposed on a daily basis contributes greatly to things like we saw today," Chittim wrote. "This is an issue that we, as an entire school community, must address together."

Classes started on time Tuesday. A meeting Wednesday night of Arundel High's principal, students and parents "is intended to be an open dialogue" following the incidents.
